Technical Improvement of the fishing gear ‘trawl’ in order to enhance its use and achieve energy efficiency. The conclusions from several RTD projects conducted by the Institute for Marine Biological Resources and Inland Waters show that there is a great need to redesign the fishing gear ‘trawl’ in a scientific way based on the vessel characteristics and its equipment in order to achieve the following goals:

  • improve its use and productivity by allowing the increase of fishing speed by 2 fold,
  • minimize energy losses due to friction of the trawl components in the water,
  • redesign the trawl using modern CAD/CAM/CAE tools and hydrodynamic models,
  • redesign the main frictional components such as the doors and recalculate the angle of attack
